摘要: This paper discusses the calculation of input referred noise contribution a switched-capacitor (SC feedback DAC to continuous-time (CT) sigma-delta (/spl Sigma//spl Delta/) modulator. Such hybrid CT/SC modulator combines high speed and implicit anti-aliasing filter CT loop with greater jitter immunity SC DAC. A simple expression for total circuit this type /spl Delta/ is derived.
